The HR80UK provides individual wireless radiator control withmulti point boiler interlock in heating systems where zoning is required. Itcan be fitted easily to almost any conventional radiator valve.

The associated controller (eg evotouch or CM927) provides the setpoint via thewireless user interface. The internal sensor of the HR80UK measures the localair temperature, compares this with the setpoint and adjusts the valve untilthe desired temperature is attained.

If the HR80UK detects asudden drop in temperature (ie if a window or door is opened) then the valvewill be moved to a closed position to save energy. Normal operation will beresumed automatically once the window or door is closed.

The HR80UK can be manually adjusted to temporarilyoverride the set temperature from the controller. This will create a demand andfire the boiler, until the next switching time at the controller.

Fits most TRV bodies with 30mm connecting ring. 

Hardly used, almost new. No box and no batteries
